The raven paradox notes that, at least formally, if seeing a black raven is evidence for the claim "all ravens are black", then so is any observation of anything that is neither black nor a raven. This is meant to highlight a problem in philosophy of science.

A great gift for a philosopher of science, or professors and students in philosophy.
